When the new World Superbike Championship was introduced in 1988, Honda had an issue as its highly successful custom-built RVF750 factory endurance racer (not the RC45) wouldn’t be eligible to compete. So they set out to create a new top-shelf, street-legal, limited edition race bike, producing the minimum number of units required to satisfy homologation rules. Knowing it would only have to turn out a relatively small batch of machines, Soichiro Honda wanted to use the new model to demonstrate what its factory race department was capable of. The result was a no-expense-spared race-grade legend brimming with features previously reserved for track-only machinery. Japan and Europe called it the VFR750R, but the bike we fell in love with in America was named the RC30.
At the heart of the RC30 was a liquid-cooled, 748cc, 90-degree V4 engine with four valves per cylinder, gear-driven double-overhead cams, titanium connecting rods, forged two-ring pistons, an 11.0:1 compression ratio, and a “big bang” firing order. Paired with a six-speed transmission with a trick slipper clutch, the sophisticated V4 made 118 hp at 11,000 rpm and 55 ft-lbs of torque at 9,800rpm (unrestricted). The VFR750R had a best-in-class dry weight of 396 lbs and a wet weight of 488 lbs, which was almost 10 lbs less than the game-changing Suzuki GSX-R750. The VFR had a top speed of over 150mph, and thanks to an incredibly high gear ratio, could break 80 mph in first gear.
The RC30 got fully-adjustable Showa suspension fore and aft — 43mm telescopic forks up front and a monoshock out back. Braking duties went to a pair of fully floating 310mm discs bit by four-piston Nissin calipers in the front and a single 220m unit pinched by a dual-pot caliper in the rear. The bike’s fork sliders also allowed the front calipers to remain in place during wheel changes, a feature that, like the ELF-designed single-sided swing-arm, was born out of competition for ultra-quick pit stops.
This RC30 is completely original down to the Dunlop K755 (front) and Dunlop K855 (rear) tires, which were OEM spec in certain markets).
